Food sterilizing apparatus of the present invention includes an air curtain forming means for producing a steam air curtain which prevents ambient air flow into a pressure regulating chamber and a heating and sterilizing chamber. Further, a pressurized fluid tank is fluid connected via a pipe to a pressurized fluid source and the pressure regulating chamber, so that the inner pressure of the pressure regulating chamber can be rapidly increased.
